Recommendations• The user can select the data rate from a range of 9.6 kbps to 12 Mbps. This selection, made when starting up the network, applies to all

the bus subscribers.

• The maximum segment length is in inverse proportion to the data rate.

• Repeaters can be used to cover greater distances.

• The bus ends with a line terminator at each end of the segment.

• Do not connect more than 32 stations per segment without a repeater, or more than 127 with a repeater.

• Keep the bus away from the power cables (clearance of at least 30 cm (11.9 in).

• If it is necessary for power cables to cross each other, be sure they cross at right angles.

Configuration

Coding the drive addressAn Altivar 312 is identified on the bus by its address, coded between 0 and 126.The address corresponds to the binary number given by position 0 (up/OFF) or 1 (down/ON) of the 7 switches on the left of the card.

The least significant bits are on the right.

The table below indicates the positions of the switches for all configurable addresses:

• Addresses 0 and 1 are usually reserved for the PROFIBUS DP masters and must not be used to configure the PROFIBUS DP address on an Altivar 312.

• It is not advised to use address 126, which is incompatible with SSA service (Set Slave Address) and with some network configuration softwares (Sycon, ...).

Example for DP address = 2:

Dip switch 8 is not connected.

Configuration

Control of an ATV 312 from a PROFIBUS DP option cardThere are several ways to control an ATV 312 from a communication card:

• The control word and the speed reference are controlled from the network in the same time. • The control word and the speed reference come from separate sources.

However, separate mode is only allowed when the [ACCESS LEVEL] (LAC) parameter in the [COMMAND] (CtL-) menu is set to L3.The control of the drive is also detailed in the programming manual of the ATV312 in the chapter "Control Menu".

Control of the drive when LAC = L1 or L2There is no particular settings, the channels are managed in order of priority.

Control of the drive when LAC = L3 When configured with LAC = L3, several configurations are possible:

• Control and reference come from the communication card,• Control via PROFIBUS DP or the terminals in native profile (CiA402),• Control is separated from reference channel.

Configure the following parameters:

Only the master can initialize communication. The slaves behave like servers responding to requests from masters.

Several masters can coexist on the same bus. In this case, the slave I/O can be read by all the masters. However, a single master has writeaccess to the outputs. The number of data items exchanged is defined at the time of configuration.

A GSD file contains the configuration information for the Altivar 312 with PROFIBUS DP. This file is used by the PLC during the configurationphases.The GSD file is unique to the whole Altivar 312 range. It does not describe the drive parameters, just the communication information. Thisfile appears on the CD-ROM supplied with the drive.

The PROFIBUS DP card for Altivar 312 drives supports Type 5 (Byte-String 28) cyclic frames in PPO (Parameter-Process Data-Object)format.

Type 1 PPO cyclic frames feature 6 periodic variables that are used for 2 types of service:• I/O exchanges (PZD)• Aperiodic exchanges (PKW) for parameter setting, configuration and diagnostics

PKW aperiodic exchanges are included in the cyclic frames and do not require special frames. An aperiodic exchange is used to read orwrite a parameter. The Altivar 312 PKW service is the same as the one for the Altivar 61/71 with the VW3 A3 307 PROFIBUS DP option.

PROFIBUS DP mapping

Output PZDsThe first eight bytes contain an aperiodic request (PKW) to write or read a parameter.The remaining 4 bytes contain the output PZDs (written from the PROFIBUS DP master).

Cyclic control and adjustment parameters:

PZD1: Communication scanner output word 1 (NC1)

PZD2: Communication scanner output word 2 (NC2)

The default assignment of the periodic output data is:• PZD1 = Command word• PZD2 = Speed target

Input PZDsThe first eight bytes contain the response (PKW) to the aperiodic read/write request.The remaining 4 bytes contain the input PZDs (read mode).

Cyclic monitoring parameters:

PZD1: Communication scanner input word 1 (ETA)

PZD2: Communication scanner input word 2 (RFRD)

The default assignment of the periodic input data is:• PZD1 = Status word (ETA)• PZD2 = Output speed (RFRD)

Integration of the ATV312 in a PROFIBUS DP networkcontrolled by a Modicon TSX P57 354M

The following chapter describes how to integrate an ATV 312 equipped with a VW3 A312 07 option module on a PROFIBUS DP basedconfiguration.

Configuration of the communicationWith Unity, cyclic exchanges between the PROFIBUS DP master (TSX Premium PLC + TSX PBY100 module) and the Altivar 312 take theform of input words %IWxy.0.k and output words %QWxy.0.k, where "x" = number of the PLC rack and "y" = location of the PROFIBUS DPmodule in the PLC rack.

Project configurationThe TSX Modicon PLCs can be used as PROFIBUS DP Master Device in association with the PBY 100 Profibus card.

Configuration with SyCON additional SoftwareTo configure an ATV312 as a slave device on the PBY 100 master, you must configure the PROFIBUS DP with the SyCON configurationtool. For the first time configuration, you must add the GSD file of the ATV312 (available on Schneider-electric.com) to the configuration tool:

• File Menu > Copy GSD file Once done, you can add a slave device by selecting:

• Schneider Electric as Vendor • Altivar 312 as slave Device

Configuration of the slaveDefine the address, in accordance with the DIP switches of the VW3 A312 07, and define a name to the Device.There are no additional configurations given that the Altivar 312 PROFIBUS DP module provides an unique mapping.

S1A10386 10/2009 25


Save the projetWhen all your PROFIBUS DP network devices are configured save the project and export it to Unity.

In the PBY 100 configuration tab of the project you may load now the file generated by SyCON. You can check the %IW and %QW linkedto the slave device by selecting its number (2 in the example above).

The Altivar control process using the communication bus is based on the CiA 402 profile status chart compatible with the IEC 61800-7standard. Each state represents an aspect of the internal behaviour of the drive.

This chart evolves according to whether the control word is sent (CMD W8501) or an event occurs (example: lock following malfunction).The drive status can be identified by the value of the status word (ETA W3201).

Not ready to switch on (Initialization):Communication is being initialized.Transient state invisible to the communication bus.

Switch on disabled (Configuration):Initialization of the drive is complete.The configuration and adjustment parameters can be modified.If all or part of the configuration and settings are to be loaded, we recommend disabling the consistency check function during the transfer(CMI W8504, bit 15 = 1). On completion of the transfer, the consistency check must be enabled (CMI W8504, bit 15 = 0).The drive is locked.

Ready to switch on and Switched on (Drive initialized):The drive is locked.The power stage of the drive is ready to operate, but voltage has not yet been applied to the output.The configuration and adjustment parameters can be modified, but modifying a configuration parameter returns the drive to the "Switch ondisabled" state.

Operation enabled (Operational):The drive is unlocked and voltage can be applied to the motor terminals.[Auto tuning] (tUn) requires an injection of current. The drive must therefore be in this state to perform this command.The adjustment parameters can be modified even if a run command or a DC injection current is present. However, a configuration parametercan only be modified if the motor is stopped, and this returns the drive to the "Switch on disabled" state.

Quick stop active (Emergency stop active):Fast stopRestarting is only possible after the drive has changed to the "Switch on disabled" state.

Malfunction reaction active (Reaction on fault detection):Transient state during which the drive performs an action appropriate to the type of detected fault.

Malfunction (Detected fault):The drive is locked.

Difference between a fast stop and a Quick stopA fast stop (CMD = 16#400F) is a stop on a short ramp that maintains the drive in the "Operation enabled" state.The drive remains locked after a fast stop.A run command can be executed immediately after a fast stop.

A Quick stop (CMD = 16#0002) is an emergency stop that causes a stop on a short ramp followed by locking in the "Quick stop active" state.To be able to restart the drive, you must first change to the "Switch on disabled" state via the "Disable voltage" command (CMD = 16#0000).It is not possible, therefore, to execute a run command immediately after a Quick stop.

Note:In access level L1 or L2 (parameter LAC):• Priorities between channels are managed by the drive.• At switch-on, the drive is in control via the terminals and changes automatically to the "Operation enabled" state. This means that, when

a run command is applied (for example: CMD = 16#000F), it starts without needing to follow the IEC 61800-7 status chart procedure.

When the drive is controlled via a communication bus, it is advisable to configure the access level LAC = L3:• The active channel is set by configuring the following parameters: [Profile] (CHCF), [Ref. 2 switching] (rFC), [Cmd switching] (CCS), [Cmd

channel 1] (Cd1), [Cmd channel 2] (Cd2), [Ref.1 channel] (Fr1) and [Ref.2 channel] (Fr2).• At switch-on, the drive configured for control via the bus changes to the "Switch on disabled" state. This means that it must follow the IEC

61800-7 status chart procedure to be able to start, and to help prevent any unwanted behaviour.

CMD control word (W8501)

(1)This bit action depends on the [ACCESS LEVEL] (LAC) parameter and the functions configured by the user.For example, to use bit 15 to switch the ramp, simply configure LAC = L3 (Access to advanced functions and management of mixed modes) and set the [Ramp switch ass.] (rPS) configuration parameter to Cd15.
